Hong Kong voters cast ballots in legislative elections Sunday that will help determine the eventual shape of the full democracy that Beijing has promised the former British colony. The amount of support voters give to pro-democracy and pro-Beijing camps will indicate the level of desire for political reform in Hong Kong. Beijing has pledged to allow Hong Kong’s residents to choose their leader by 2017 and all lawmakers by 2020, but no road map has been laid out. Lawmakers elected in Sunday’s polls will help shape the arrangements for those future elections.
